Create Offhost Backup Configuration Files

Create Offhost Backup Configuration Files

To set up offhost backup, you must create these configuration files on the media server

(described in the following sections):

◆ /usr/openv/volmgr/database/3pc.conf

◆ /usr/openv/volmgr/database/mover.conf

Note These files are needed only for the Third-Party Copy Device or NetBackup Media

Server backup methods. If not using either of these backup methods, you do not

need to create these files.

The 3pc.conf and mover.conf Files: An Overview

The NetBackup media server needs certain information about the devices available on the

SAN in order to coordinate an offhost backup. This information is provided in two files:

◆ 3pc.conf:

Identifies the client disks on the SAN that can be backed up, and the robotic

libraries/tape drives on which NetBackup can store the data. The NetBackup media

server uses this information to access client disks when performing an offhost backup.

It also uses this information to generate the SCSI Extended Copy commands required

by third-party copy devices.

◆ mover.conf:

Identifies the third-party copy devices. These are devices that can execute the SCSI

Extended Copy commands. A variety of devices can be designed to operate SCSI

Extended Copy, such as routers, bridges, robotic libraries, and disk arrays. The

mover.conf file is needed for the Third-Party Copy Device backup method only, not

for the NetBackup Media Server method.

3pc.conf Description

In the 3pc.conf file, each SAN device needs a one-line entry containing several kinds of

values. The values required depend on several factors (explained below). Typically, these

include (but are not limited to) the device ID, host-specific device path, and serial number.

One or more of the following are also required: the identification descriptor, logical unit

number (LUN) and world-wide port name. See “Determining Requirements” on page 61.

Some of this information will be automatically discovered and filled in by the bptpcinfo

command, as described under “What bptpcinfo Automatically Provides” on page 61. The

procedure for using the bptpcinfo command is under “Create the 3pc.conf File” on

page 65.
